I use a web based CRM for work, and it’s pretty good. That said, I wrote a chrome extension to slightly improve it in dozens of small ways. The cumulative effect of these changes is that I have a quantitively and qualitatively different experience than everyone else using this software.
Working remotely, where so much of the information comes through a web browser, being able to force a website to work the way I prefer feels like an infinity stone level reality warping super power.
